摘要
通过平行试验的方法,研究水泥稳定碎石路面基层材料在不同龄期和不同配合比下的无侧限抗压强度和劈裂强度,从而评价水泥稳定碎石的力学性能。结果表明:配合比对水泥稳定碎石的力学性能有直接影响;而且水泥掺量越高,水泥稳定碎石的强度也会越高;水泥稳定碎石初期强度比较高,后期会继续增长。研究结果可为实际施工提供一定的理论依据。
The unconfined compressive strength and splitting strength of cement stabilized aggregate base with different curing ages and mix proportions were studied with parallel test, and the mechanical properties of cement stabilized aggregate base were evaluated. The results show that mix proportion has direct impact on the mechanical properties, with bigger cement content yielding higher strength; the initial strength of cement stabilized aggregate is at high level, and continues to grow in later period. The research results provide theoretical basis for practical construction of cement stabilized aggregate base.
